Ebay head,change valve stem seals?

[Indian]

I orginally had bought a rebuilt head off ebay,it came with everything except cam gears. I already planned on replacing the valve stem seals,so I bought supertech seals. I was wondering if it would be a better idea to leave the seals that came in the head,or if supertech are really going to seal better. Any input is appreciated thanks guys.

look at the seals, if they are a bright blue, they should be the hi-temp vition seals.

there are other seals out there that are just fine, I just perfer the vitons

I never trust the seals that come in any head. If there's any question as to their type or condition, change them now and save yourself a lot of work later.

Ok thankyou for your input guys,I might as well change them out since I allready have them.
